By reading the impressions on Headfi, it seems that the chassis might be repurposed for future builds. By including the "balanced in" (should really be called xlr instead) the front/chassis is already ready to go IF a future balanced offering becomes a reality. Since most of the internals needs to be doubled it still might be a tight fit. Then again I don't know what the inside of a production unit looks like. A second offering seems like a good chance of happening given the amount of units that are already pre-sold, not to mention how MD likes to squeeze the max out of their collaborations with manufacturers.
